+**Lightning Wallet Integration:**
+The app integrates with LNbits for Lightning Network wallet functionality with real-time balance updates:
+
+**Core Wallet Services:**
+- `src/core/services/PaymentService.ts` - Centralized payment processing and wallet balance management
+- `src/modules/wallet/services/WalletService.ts` - Wallet operations (send, receive, transactions, pay links)
+- `src/modules/wallet/services/WalletWebSocketService.ts` - **Real-time balance updates via WebSocket**
+
+**WebSocket Real-Time Features:**
+- **Automatic balance updates** when payments are sent or received
+- **Live transaction notifications** with toast messages
+- **Connection management** with automatic reconnection and exponential backoff
+- **Battery optimization** via VisibilityService integration (pauses when app not visible)
+- **Unit conversion handling** between sats and millisats for different LNbits WebSocket behaviors
+
+**WebSocket Configuration** (in `app.config.ts`):
+```typescript
+websocket: {
+  enabled: true,           // Enable/disable WebSocket functionality
+  reconnectDelay: 1000,    // Initial reconnection delay
+  maxReconnectAttempts: 5  // Maximum reconnection attempts
+}
+```
+
+**How WebSocket Balance Updates Work:**
+- Connects to LNbits WebSocket: `wss://your-lnbits/api/v1/ws/{walletInkey}`
+- Handles both incoming and outgoing payment notifications
+- **Incoming payments**: Uses balance as-is (post-payment balance from LNbits)
+- **Outgoing payments**: Adjusts balance by subtracting payment amount (pre-payment balance from LNbits)
+- Updates stored in `PaymentService.updateWalletBalance()` for consistency
+- Triggers Vue reactivity to update UI components immediately
+
 **Nostr Integration:**
 The app connects to Nostr relays using a custom NostrClient class built on nostr-tools. Key files:
 - `src/lib/nostr/client.ts` - Core Nostr client implementation

+A modular Vue 3 + TypeScript application with Nostr protocol integration and Lightning Network wallet functionality.
 
-Learn more about the recommended Project Setup and IDE Support in the [Vue Docs TypeScript Guide](https://vuejs.org/guide/typescript/overview.html#project-setup).
+## Features
+
+- **Modular Architecture**: Plugin-based system with dependency injection
+- **Nostr Integration**: Decentralized social networking and messaging
+- **Lightning Wallet**: Real-time balance updates with LNbits WebSocket integration
+- **Event Ticketing**: Lightning-powered event tickets and marketplace
+- **PWA Support**: Progressive Web App with offline capabilities
+- **Desktop App**: Electron-based desktop application
+
+## Real-Time Wallet Features
+
+The application provides seamless Lightning Network wallet integration:
+
+- **Instant Balance Updates**: WebSocket connection provides real-time balance updates when payments are sent or received
+- **Live Notifications**: Toast notifications for incoming payments
+- **Connection Management**: Automatic reconnection with exponential backoff
+- **Battery Optimization**: Pauses WebSocket when app is not visible to save battery
+- **Multi-Wallet Support**: Manages multiple Lightning wallets with the first wallet as default
+
+### WebSocket Configuration
+
+Configure WebSocket behavior in `src/app.config.ts`:
+
+```typescript
+modules: {
+  wallet: {
+    enabled: true,
+    config: {
+      websocket: {
+        enabled: true,           // Enable/disable real-time updates
+        reconnectDelay: 1000,    // Initial reconnection delay (ms)
+        maxReconnectAttempts: 5  // Maximum reconnection attempts
+      }
+    }
+  }
+}
+```
+
+## Development
+
+```bash
+# Install dependencies
+npm install
+
+# Start development server with hot reload
+npm run dev
+
+# Build for production
+npm run build
+
+# Run Electron desktop app
+npm run electron:dev
+```
+
+## Environment Setup
+
+Required environment variables:
+
+```bash
+# LNbits server URL for Lightning wallet functionality
+VITE_LNBITS_BASE_URL=http://localhost:5000
+
+# Nostr relay configuration (JSON array)
+VITE_NOSTR_RELAYS='["wss://relay1.example.com","wss://relay2.example.com"]'
+```
+
+## Architecture
+
+The application follows a modular architecture with the following core modules:
+
+- **Base Module**: Authentication, Nostr client, PWA functionality
+- **Wallet Module**: Lightning payments, WebSocket balance updates, transaction management
+- **Events Module**: Event ticketing with Lightning payment integration
+- **Market Module**: Nostr marketplace functionality
+- **Chat Module**: Encrypted messaging via Nostr
